- the second latching elements 130 and 132 are associated with the Hartvidabsaug réelle 12.
- a basic position defining detent position as shown schematically in Figure 6, are the first locking elements 128 with the second locking elements 130 into engagement.
- the latching projection 84 forms a biasing element 134 of the Rastverstellmechanismus 126, which holds the first and second latching elements 128 and 130 in the basic position of the Rastverstellmechanismus 126 shown schematically in Figure 6 in the locked position.
- the Saugkanalhülse 62 can be rotated relative to the housing 16. In order to achieve this, however, the biasing element 134 has to be pivoted somewhat in the direction of the axis of rotation 66 so that the first latching element 128 and the second latching element 130 are disengaged. If the suction channel sleeve 62 is rotated slightly further, the first latching element 128 engages in the second latching element 132, that is to say the guide section 104. In However, this is a continuous rotation of the Saugkanalhülse 62 about the axis of rotation 66 relative to the housing 16 in an angular range of about 160 ° possible.
- the biasing member 134 is formed on the second clutch device 52 as described. Alternatively, it would also be conceivable to arrange the biasing element 134 on the first coupling device 50. It is in the form of a spring, in the form of a leaf spring formed.
- the Hart vomunabsaug réelle 12 further includes a rear part 136 for automatically transferring the suction nozzle 30 and the Hartvidaug- device 12 from a relative to the basic position shown schematically in Figure 14 due to a rotation about the rotation axis 66 deflected rotational position back to the normal position. Examples of deflected rotational positions are shown schematically in FIGS. 9 and 15.
- the rear part device 136 includes a return element 138 in the form of a spring element 140 defining coil spring 116. This acts as described on the one hand to the Saugkanalhülse 62 and thus indirectly to the suction nozzle 30 and the other part of the housing 16 of the Hart vomabsaug réelles 12.
- the spring element 140 may be formed in the form of a leaf spring or a torsion spring.
- FIGS. 8 and 9 show the functioning of the rear-part device 136 schematically in FIGS. 8 and 9.
- Figure 8 shows the basic position of the Hart vomabsaug réelles 12, which corresponds to the locking position of the Rastverstellmechanismus 126 as shown in Figure 6.
- the latching elements 128 and 130 engage in one another.
- the suction nozzle 30 is rotated about the axis of rotation 66 relative to the Hartvidaug réelle 12, for example, as shown schematically in Figures 9 and 15 in a clockwise direction facing the suction nozzle 30, so takes one of the end surfaces 94 with the end portion 120 in the clockwise direction. However, the end portion 118 continues to abut against the end face 114, which is substantially diametrically opposed to the axis of rotation. As a result, the coil spring 116 is slightly contracted. The farther the suction nozzle is deflected clockwise from the basic position, the greater is the applied force in order to achieve the deformation of the coil spring 116.
- the return element 138 forces the suction nozzle 30 back into the normal position.
- the other end face 94 similarly absorbs the end section 118 of the helical spring 116 and thus in turn leads to a compression of the helical spring 116.
- locking device may be provided which prevents rotation of the suction nozzle 20 relative to the housing 16.
- a locking can be realized by a movement of the locking projection is prevented, so that the locking lug 86 can not escape from the recess 106.
- suction nozzles and Hart vomabsaug marén may optionally be provided a ball joint.
- a joint ball which is arranged either on the housing or on the suction nozzle in a corresponding hollow-dome-shaped recess, which is then arranged or formed in each case on the other part of the Hart horrittivitessg réelles.
- the suction channel 36 may optionally be passed through the ball joint or by means of a flexible hose or tube on the conical joint. In such an embodiment, therefore, the function of the rotation of the suction nozzle relative to the housing is separated from the guidance of the suction flow.
- the exemplary embodiment of a hard surface cleaning device 10 shown by way of example in the figures enables in particular a compact construction same, because the cooperating first and second coupling means 50 and 52 not only form the hinge 122, but also at the same time in cooperation a portion of the suction channel 36.
- a rotatably supported on the housing 16 bearing shaft in the form of rotatably coupled to the suction passage 58 suction channel sleeve 62 is thus hollow and not only defines the axis of rotation 66 with its longitudinal axis, but also the suction channel 36.
